Patients who receive a large number of blood transfusions may develop a problem in which they have too much iron in their blood. Deferasirox is an iron chelator; this medication works by pulling iron out of the bloodstream so that it is excreted when the patient uses the bathroom.
Patients who suffer from liver or kidney disease should not take this medication. Deferasirox makes it more likely that a patient will have a liver or kidney problem. Patients should contact their doctors right away if they have any of the following problems:
- Extreme fatigue
- Severe pain in the stomach or lower back
- Changes in urination frequency or difficulty urinating
- Black, tarry stools or brown urine
Patients should also refrain from taking aspirin or other blood-thinning medications with Deferasirox in order to reduce the risk of excessive bleeding or internal bleeding in the stomach or intestines.
